OBJECTIVES: Behçet's disease (BD) has been recognized as an unclassified type of vasculitis with an accompanying tendency to thrombosis. No disease-specific pathology has been demonstrated so far to explain the prothrombotic state, and this predisposition is considered to be associated with endothelial activation/dysfunction. P-selectin glycoprotein ligand-1 (PSGL-1) variable number of tandem repeat (VNTR) polymorphism has an impact on the protein length, and heterozygosity affect of the PSGL-1 to P-selectin interaction, which has been found to be associated with an increased risk of thrombosis in patients with antiphospholipid syndrome...

BACKGROUND: The molecular pathomechanisms underlying atrial thrombogenesis are multifactorial and still require detailed investigations. Transgenic mice with cardiomyocyte-directed expression of the transcriptional repressor CREM-IbΔC-X (CREM-TG) represent an experimental model of atrial fibrillation (AF) that shows a gradual, age-dependent progression from atrial ectopy to persistent AF. Importantly, this model develops biatrial thrombi. The molecular characteristics related to the thrombogenesis in CREM-TG mice have not been studied, yet...

Platelet function tests are mainly used in the diagnostic work-up of platelet disorders. During the last decade, the additional use of platelet function tests to evaluate the effect of antiplatelet therapy has also emerged in an attempt to identify patients with an increased risk of arterial thrombosis. Furthermore, platelet function tests are increasingly used to measure residual effect of antiplatelet therapy prior to surgery with the aim of reducing the risk of bleeding. To a limited extend, platelet function tests are also used to evaluate hyperaggregability as a potential marker of a prothrombotic state outside the setting of antiplatelet therapy...

Activated protein C resistance (APCR) describes a hemostatic disorder characterized by a poor anticoagulant response to activated protein C (APC). This results in an increased risk of venous thrombosis, including deep vein thrombosis and pulmonary embolism. Protein C is a natural anticoagulant that is synthesized in the liver and is activated to APC via proteolysis. APC then degrades Factors Va and VIIIa. APCR describes the reduced inability of APC to cleave Factors Va and VIIIa, which therefore promotes increased thrombin generation and potentially leads to a prothrombotic state...

Venous thromboembolism, usually entailing deep vein thrombosis, pulmonary embolism, or both, is a complex and multifactorial disorder, in which a number of putative conditions interplay and finally contribute to propel the individual risk over a certain degree, so ultimately culminating in the development of venous occlusive disorders. Thrombophilia is commonly defined as a propensity to develop venous thromboembolism on the basis of an underlying hypercoagulable state attributable to inherited or acquired disorders of blood coagulation or fibrinolysis...

Sudipta Biswas, Alejandro Zimman, Detao Gao, Tatiana Byzova, Eugene Podrez
Rationale: Platelet hyperreactivity, which is common in many pathological conditions, is associated with increased atherothrombotic risk. The mechanisms leading to platelet hyperreactivity are complex and not yet fully understood. Objective: Platelet hyperreactivity and accelerated thrombosis, specifically in dyslipidemia, have been mechanistically linked to accumulation in the circulation of a specific group of oxidized phospholipids (oxPCCD36) that are ligands for the platelet pattern-recognition receptor CD36...

First described in the early 1980s, antiphospholipid syndrome (APS) is a unique form of acquired autoimmune thrombophilia in which patients present with clinical features of recurrent thrombosis and pregnancy morbidity and persistently test positive for the presence of antiphospholipid antibodies (aPL). At least one clinical (vascular thrombosis or pregnancy morbidity) and one lab-based (positive test result for lupus anticoagulant, anticardiolipin antibodies and/or anti-β2-glycoprotein 1 antibodies) criterion have to be met for a patient to be classified as having APS...

Chronic kidney disease (CKD) patients are at high risk for thrombotic events. Indoxyl sulfate (IS) is one of the most potent uremic toxins that accumulates during CKD. Even though IS is associated with an increased risk for cardiovascular disease, its impact on thrombotic events still remains not fully understood. The purpose of the study was to evaluate the direct effect of IS on thrombotic process. We examined the impact of acute exposure to IS on thrombus development induced by electric current in Wistar rats, intravital thrombus formation after laser-induced injury in the mice endothelium, coagulation profile, clot formation dynamics, platelet aggregations, and erythrocyte osmotic resistance...

Previous study has demonstrated that activation of the mammalian target of rapamycin (mTOR) pathway in endothelial cells (ECs) results in the formation of chronic vascular lesions associated with antiphospholipid syndrome (APS). In addition, it has been shown that stimulation of monocytes and ECs by antiphospholipid antibodies (aPL) leads to a prothrombotic and proinflammatory state and up-regulated expression of tissue factor (TF) and inflammatory cytokines. However, the role of mTOR in pathogenic mechanisms of APS remains largely unexplored...

BACKGROUND: Platelets play a central role in myocardial infarction, and platelet activity can be evaluated with platelet indices including, platelet distribution width (PDW) and plateletcrit (PCT). These indices have been demonstrated as markers of prothrombotic state in cardiovascular diseases. Therefore, we aimed to investigate, the usefulness of these biomarkers in ST-elevation myocardial infarction (STEMI) in young patients. METHODS: This cross-sectional study consisted 565 subjects which classified into three groups: group 1 (168 young patients with STEMI), group 2 (173 non-young patients with STEMI), and group 3 (224 age-matched controls with angiographically normal coronary arteries)...

BACKGROUND: While twin studies indicate a genetic component in arterial thrombosis such as ischemic stroke, myocardial infarction (MI), or peripheral arterial occlusive disease (PAOD), the clinical relevance of hemostatic polymorphisms in arterial thrombosis is a matter of debate. METHODS: We analyzed the prevalence of 13 hemostatic polymorphisms [PAI-1, PLAT, F5 (including factor V Leiden and HR2 haplotype), F2, F7, F13A, FGB, TFPI, THBD, MTHFR, ACE, and ITGA2] in patients referred to a tertiary referral center...

BACKGROUND: Declining platelet counts may reveal platelet activation and aggregation in a postoperative prothrombotic state. Therefore, we hypothesized that nadir platelet counts after on-pump coronary artery bypass grafting (CABG) surgery are associated with stroke. METHODS: We evaluated 6 130 adult CABG surgery patients. Postoperative platelet counts were evaluated as continuous and categorical (mild versus moderate to severe) predictors of stroke. Extended Cox proportional hazard regression analysis with a time-varying covariate for daily minimum postoperative platelet count assessed the association of day-to-day variations in postoperative platelet count with time to stroke...

BACKGROUND: A prothrombotic state is associated with the presence and severity of organ damage in hypertensive patients. In these patients, evidence of subclinical carotid functional changes anticipates major cardiovascular events. The aim of this study was to investigate the association of hemostatic markers with carotid artery stiffness in hypertension. MATERIALS AND METHODS: In 116 untreated essential hypertensive patients recruited at a referral center in the University of Udine, we assessed common carotid artery stiffness by B-mode ultrasonography and measured plasma fibrinogen, D-dimer, plasminogen activator inhibitor-1 (PAI-1), and homocysteine by the currently available methods...

BACKGROUND: Deep vein thrombosis (DVT) is one of the major complications of total joint arthroplasty (TJA). Chronic kidney dysfunction (CKD) has proven to promote a proinflammatory and prothrombotic state and is prevalent among patients undergoing TJA. The purpose of this study is to identify whether CKD increase the risk of DVT following TJA. METHODS: In a retrospective study, 1274 patients who underwent primary TJA were studied. CKD is graded in 5 stages. Univariate and multivariate analysis were used to identify the association of CKD and its severity with postoperative DVT...

The aim of the present study was to investigate the effect and the underlying mechanism of the combined treatment of rhynchophylla total alkaloids (RTA) and sinapine thiocyanate for protection against a prothrombotic state (PTS) associated with the tumor necrosis factor-alpha (TNF-α)-induced inflammatory injury of vascular endothelial cells (VECs). A TNF-α-induced VEC inflammatory injury model was established, and cell morphology of VECs was evaluated using scanning electron microscopy. In addition, reverse transcription-quantitative polymerase chain reaction and western blot analysis were performed to examine the mRNA and protein expression of coagulation-related factors, including nuclear factor-κB (NF-κB), transforming growth factor-β1 (TGF-β1), tissue factor (TF), plasminogen activator inhibitor (PAI-1), protease-activation receptors (PAR-1) and protein kinase C (PKC-α) in VECs...

Non-cirrhotic, non-malignant portal vein thrombosis (PVT) is commonly secondary to inherited or acquired prothrombotic states. However, even after extensive workup, 25% of patients with PVT have no apparent prothrombotic aetiology identified (idiopathic PVT). Inherited conditions include factor V Leiden, PT mutation and protein C/S/AT deficiency. Acquired conditions include APS, PNH and BCR-ABL 1-negative myeloproliferative neoplasms (MPN). BCR-ABL-1 negative MPNs are the most frequent underlying prothrombotic risk factor for PVT (15%-30%)...

BACKGROUND AND PURPOSE: Preeclampsia affects 3% to 8% of pregnancies and increases risk of pregnancy-associated stroke (PAS). Data are limited on which women with preeclampsia are at highest risk for PAS. METHODS: Using billing data from the 2003 to 2012 New York State Department of Health inpatient database, we matched women with preeclampsia and PAS 1:3 to preeclamptic controls based on age and race/ethnicity. Pre-defined PAS risk factors included pregnancy complications, infection present on admission, vascular risk factors, prothrombotic states, and coagulopathies...
